This invention relates to conveyor mechanisms, `and in particular to conveyor mechanisms for conveying hot articles such as glassware received from a mold or forming machine.

In automatically conveying glassware from the forming machine to an annealing leer, for example, it is of prime importance to have a conveying mechanism that will not mark, check, or crack the glassware and which will deliver the ware to the leer in an upright position so that the ware will not be distorted out of shape.

V Also, the amount Vof time during which the L ware is exposed to the atmosphere after leaving the yforming machine and before it enters the leer, must be controlled in order to produce the best annealing Vof glassware. For example, large, heavy ware should not be delivered to the annealing leer as soon .as small, light ware, because as it leaves the forming machine it carries an excess of heat, which must be given oli' before entering the leer,

V otherwise the excess heat will cause the ware d to lose its shape while being annealed.

On the other hand, small, light ware should be delivered to the leers as soon as possible after leaving the mold or forming machine, since it cools quickly with the resulting tendency to set up detrimental strains in the ware. l

Gonveyors for hot articles such as glassware are now in use, but all such devices y known to me are more or less unsatisfactory, in'that a high percentage of the ware is cracked, broken or marked by the conveyor or conveying devices.

An object of this invention is to provide a device for conveyingglassware as, for example, from a forming machine to an annealing leer which is so constructed and arranged that checking, cracking, marking and upsetting of the ware, while on the conveyor, is c substantially., if not wholly, eliminated.

A further object of my invention is to producea device which will convey the ware in an upright position and at a rat-e of speed within the control `of the operator, so that the ware may be exposed to the atmosphere the desired length of time.

A further object is to produce mechanism for automatically and eiciently conveying glassware from a forming machine to the leer which materially reduces the percentage of broken ware and thereby lowers the manufacturing costs.

A further.1 object is to produce a device having improved mechanism arranged to receive vthe ware from the forming machine take out mechanism, and to convey the same to the leer feeding mechanism.

A still further object is to produce a mechanism for automatically conveying glassware which engages only the lower surface of the ware. ,i

These and other objects which will be made apparent to those skilled in this particular art throughout the further description, are accomplished by means of this invention, one embodiment of which is described in the following specification and illustrated in the accompanying drawings, wherein:

Throughout the several figures of the drawings, like reference characters refer to like parts of the structure. e

As illustrated, my improved conveyor includes a series of closely spaced rollers arranged in alternate long and short pairs mounted in a substantially horizontal plane.v

The conveyor rollers are constantly driven fromV a common source so that all the roller rotate at the same speed. y The ware. as it leaves the forming machine, is delivered to a ware-receiving mechanism which is mounted over the front or receiving end of the conveyor. The ware-receiving mechanism consists essentially .of an adjustable vertically reciprocating member provided with a yseries of normally idle but rotatably mounted rollers -on which the ware is placed by the forming Vmachine take out mechanism. The reciprocating member is synchronized with the formingmachine take out mechanismso that it moves to receive eachV article delivered by the take out mechanism. When the reciprocating member moves to a position such that it cooperates with the conveyor, the normally idle rollers carried by it, come into Contact with a series of rollers associated with the conveying mechanism and which are rotating inthe opposite direction from the rollers of the conveyor. The rollers of the reciprocating member by such engagement are thereby rotated inthe same direction as the conveying rollers of the conveyor, and move the article carried thereon to the conveyor.

The conveyor rollers deliver the glassware to a constantly rotating disc member located at the rear end of the conveyor and in front of the leer. As the disc rotates, the ware moved onto it by the conveyor rollers is carried around into engagement with a stationary arm which deflects the ware olf of the disc and directs it onto a conveyor which carries the ware through the leer. f

So that my conveyor may be used to convey all kinds and sizes of glassware, I employ rollers which are relatively small in diameter. I prefer to use rollers which are not over 1/2 inch in diameter so that the surface of each roller forms a hair line support for the articles being conveyed. Rollers of this size do not check or chill the ware, and consequently do not Vset up strains therein.

yThese relatively small rollers are placedclose Referring to the drawings in detail, I have shown my conveyor mechanlsm mounted on a frame which comprises a front supportf ing member 10 and a rear supporting mem# ber 11. The front and rear supporting members are held in position by lower side mem- Y 16 which are arranged parallel toeach other Vand `maintained Lin proper alignment by spacers. 17 secured therebetween. The, end spacers are fastened directly to the tops ofV the supporting members.

Main convey/o1" mechanism' ,The conveyor proper comprises aseries of closely spaced rollers 18 journaled in openings vin the upper edgesof the side members 16V and arrangedin asubstantially horizontal plane therein. c

Each of the rollers 18, whichl form the main conveyor, has a portion 2O extending beyond the plane of one of the side plate members, whilethe vopposite end of the roller is substantiallyfflush with'l the outside of the other side member.

The extended port-ions 20 on adjacent roll- `ers are'disposed on opposite sides of the side members 16, while the extended portions on each side of the side members are alternately long and short. vThe rollers, therefore, arek grouped in alternately long and short pairs. f The extended portion 20 of each roller isV provided with a'sprocket wheel21 which is secured thereto by a set screw`22k extending. throughthe hub 23 ofthe wheel. Since the extendedk portions on each of the rollers on one side of the side members are alternately ylong and shortsuflicient space is providedr between the relative small rollers to permit the sprocket wheels on each of the long and short pairs to be iny alignment withv Vthe wheels on the other long andshort pairs, res 'ectively, making it possible to drive all rol ers from a common source. In order to drive all the rollers 18 of theY conveyor from `a single source on each side of the plate 16 the two pairs of rollersk at the discharge end of the conveyor, `designated as 24 and 25, respectively, are of special construction and have lon er extended portions than the remaining rol ers 18. The pair of rollers 24 which act as drivers for the conveyor, each have a portion 26 extending beyond the side members 16 on opposite sides thereof. The extended portion of each of the rollers 24 is journaled at its extreme "LOL Leonesa outer Iend ina bearing 2.57 which `is :supported in a bracket 28 (Figs. i2 vand 10) secured to the yside nrember 1&6. The portion 26 of each roller 24 has three lsprocket Wheels, `29, 8O and :81 (llig. 16)., mounted thereon which are 'so arranged that ythe sprocket Wheels ,'29 are in alignment With the sprocket Wheels 21 on the short rollers 18 and `are connected therewith by :an endless sprocket chain 32, While the sprocket Wheels 8.0 are in alignment With the Wheels A2 1 on the long rollers 18 and are connected therewith by an endless chain 33.

Each roller 24 is driven by an endless sprocket chain 34' Which passes over the sprocket 31 carried bythe extension 26, .and a sprocket Wheel 35 carri-ed by a lshaft 36 .mounted in brackets 37 secured to the side plate .members 16 (see Figs. 1, '2 and 11).. Thezshaft L36 has a sprocket Wheel 38 .secured thereto Which is connected by a'fsprocket chain `40 to the sprocket y40a on a variable yspeed Vtransmission 39. The transmission is driven by an endless :sprocket chain 41 connected Lto Ya motor 42 by means of `a suitable sprocket Wheel (F ig. rlhe motor and transmission are mounted on a plate A43 secured to the :lower vside members 1'2 of the frame.

ln onder to maintain the sprocket VWheels land 3.0 on feach `of the rollers 24 .in line with the sprocket Wheels on the short and long rollers, respectively, yso that all the con veyor rollers may be driven by the yrollers 24, the rollers 125, that is, the 'next to the last pair of rollers theiconveyor :are each provided with ya portion 44 extending beyond the side member 116 which is longer than the extending portions l2O on the long rollers 18.. Such an arrangement is necessarily due to the small diameter and the relatively close spacing of the rollers 18 comprising the `conveyor.

The rollers v25 are :each driven by a sprocket chain 47 which passes over a sprocket Wheel secured to theextended portion `44 on the rollers 25 land a sprocket Wheel 46 which is mounted lon the ends of one of lthe long pai-r of rollers, designated as 1'8", which have been made eXtra long for that purpose. The rollers 24 therefore, drive the rollers 18 through the sprocket Wheel 21 and sprocket chain 38 and these rollers turn drive the rollers 25 through the sprocket chain 47. It is to be understood that yany of the lrollers 18 maybe selected as the driving rollers for the rollers 25.

Receiving and of @orwell/or Associated With the conveyor rollers 18 at the front or Ware-receiving end oi the con veyor are a series et rollers 19 which are journaled in the side members 16 in a plane slightly lower than the plane of -the main conveyor rollers 18. These rollers '119, which 184'., around which the sprocket chains -31 are returned to :the driving rollers 24. vThe rollers 18 have gears 55 secured thereto Vloetween the side members 16 and the vsprocket Wheels `21 which mesh with gears `53 mounted on the ends of the rollers, designated Vas 54,` which are adjacent the rollers 18". The ynemaining rollers 19 are driven through a train of gears associated with the gears 53 on 'the rollers 54. Each oi2 the gears 581mesh with an idler gear 51 Which is mounted on .an idler pin 52 extending from the .side member 16. Each of the gears 52 in tur-n meshes with a gear mounted von the end off each 'of the next pair of rollers 19.. These gears 50 in Aturn mesh with another idler gear 51 vf'liich mesh With gears 50 on the next pair otroll ers 19. rlhus all the rollers 19 are driven directly by the rollers 18 which are connected to the driving rollers 24 through the sprocket chain 31.

A pair ot rollers 56 are mounted in 'th-e side members 16 adjacent the rollers 18 and above the rollers 54. The rollers 56 are in engagement With the rollers 54 and .are frictionally driven bythe rollers 54. The rollers 56, therefore, rotate in the same direction as the main conveying rollers. The rollers 56 are so arranged that the tops thereof are in the saine plane as the tops oi the rollers 18.

The rollers 19 are undercut, as at 58, to provide ample lspace for broken glass and dirt to fall :through the conveyor. lVhe-n the inachine is in opera-tion. the rollers 18 and .56 are constantly driven and caused to rotate in adirection toward the discharge end of the conveyor. while the rollers 1'9 yand 54 yat .the receivin-gend .of the lconv-ever are driven in the opposite direction. A plate 59 (Figs. 8 and 10) is secured to the top of the side members 16 and vextends over the .sprocket Wheels 21 and chains forming a shield for protect-ing the operator.

lfVcWc-receeim/ mechanism The iglassware is taken from the forming machine by ,some suitable article take out discharging mechanism associated with the forming machine and placed on a vertically ,reciprocating Ware-receiving member which is mounted over the liront or receiving end of the conveyor. The Ware-receiving mecha nismrcomprises an elevator plate 60 (Figs. 1. 4 and 8), which is .supported cna member 61, mounted on the upper end of a vertically extending piston rod 62. best shown in Figs. 3 and 8. The lower end of the rod 62 is connected to a piston 63, which is mounted in acylinder 64. The cylinder 64 is supported on a plate 65 secured to the yfront supi the forming machine soy that the elevator will be raised to ware-receiving position each time the forming machine take out mechanism swings away from the mold or forming '7mm chine.

The height to which the elevator 60 "is raised by the piston rod 62 is controlled by a combination stui'lingI box and adjusting nut 67 which is mounted in the cylinder head purpose.

and which limits the up stroke ofthe piston.

The adjusting nut 67 permits the elevator plate to be raised to the proper height under the forming machine take out mechanism regardless of the size of ware being made inthe mold. y

When the elevator plate is raised to its uppermost position, the forming machine take out mechanism, designated as 68.,y places the ware on a series of idle rollers 69, journaled in members 70 depending from the legs of a U-shaped plate 71 which is hinged to and carried by the elevator plate. The rollers 69 are formed from tubing which is journaled on rods 72 before the same aresecured in the depending members 7 0'. A channel member 71a, which is placed over the edges of the plates 60 and 71 prevent the plate 71 from tilting or tipping.v v

When the elevator plate 60 is lowered so that it cooperates with the main conveyor rollers 18 the rollers 69 are received between the rollers 19 which are spaced apart for that The rollers 19 are arranged in a plane slightly lower than the plane of the main conveying rollers 18 so that the rollers 69, when in engagement therewith, will be in the same plane as the rollers 18. As the rollers 19 are constantly rotating in a reversel direction to thek rollers 18, the rollers 69 will be rotated in the same direction as thel rollers 18, due to the frictional engagement with the rollers 19, and move the ware placed thereon by the forming machine take out mechanism onto theoonveyor rollers 18.

y To maintain the reciprocating ware-receivin'grmechanism in. proper position over the front or receiving ends of the conveyor, the

. elevator-plate 60 is provided with guide rods 75 which are slidablyrmounted in brackets 76 securedl to the front supporting member v10, and which prevent the piston rod and elevatorplate from turning relative to the cylinder.V V'The plate 60 is alsoprovided with a weight 77 which tends to'balancethe plate Y71Jand ware receiving rollers. Y

So that the rollers 69 of the ware-receiving mechanism will properly seat on the rollers 19 of the conveyor, the plate 71, carrying the "rollers, Vis provided with ka member 78 havingr a groove therein which registers with the n tongue'of a similar member 9 secured to the elevator plate 60. i This male and female arrangement acts as a guide which permits movement between the two plates and maintainsthe rollers 69 in alignment with the rollers 19. v

Ware discharging mechanism f.. The .ware moves fromthe vware receiving rollers 69 over the main conveying rollers 18 to a warefdischarging mechanism which deliversthewareto the annealing leer. The ware discharging f mechanism Acomprises a disc slidably mounted on a vvertical shaft p91 positioned at the rear of ther frame and 95, such as asbestos board, to prevent cracking and checking of the glass Ware coming in contact therewith. The disc 90 has a hub 96 provided with a longitudinal slot 97 which receives a .pin 98 whichV extends horizontally Y throughthe shaft 91. This forms a driving connection between the shaft and disc. The disc may be adjusted vertically with relation to the shaft byk an adjusting screw-99which extends through the. face of the disc and rests on the end of the shaft 91.

. The lower end of the vertical shaft 91 has a Y bevel gear100 secured thereto which meshes Vwith a bevel driving pinion 101', keyed ona horizontal shaft 102, journaled inV bearings 103,*supported on a bracket 110 secured to the rear supporting member. Set collar 104 holds the shaft 102 in position in the bearings. They shaft V102 has a sprocket wheel 105 secured thereto which -is driven by a sprocket chain 106 passing over the sprocket wheel and a sprocket wheel 107 which is secured to the driven shaft 36. When the machine is operating, the discharging disc 90 is constantly rotated by the above described mechanismand carries theware delivered thereto by the conveyorrollers 18 arounduntil' the e same comes in rcontact, with a'stationary arm or a deflector 108 which deleets the Ware off the disc on to the leer conveyor, a portion of which is indicated at 111. yThe ware is prevented from upsetting while on'the disc by an auxiliary deiiector109. f s

Operation e In operation, the ware-receiving mecha# nism is elevated, whichpositions the idle roll- 'ware onto the rotating rollers 18. The piece of ware travels across the rollers 18 onto a rotating'disc 90 which is positioned in front of the leer. The disc carries the ware around to a position infront of the leer conveyor,

'determined by an arm 108 which deflects the rware'onto the leer conveyor.

As soon as the ware'has been transferred from the rollers 69 tothemain conveyor rollers 18, the ware-receiving mechanism is again elevated and another cycle of operation is started. l

It is readily apparent from the foregoing description thatVv the speed of rotation ofthe conveyor rollers may be so regulated that the ware will be Vconveyed to the leer at the desired or ideal rate of speed and in a certain elapsed time after leaving the forming machine. Such a speed control makes it pos sible to handle any size ware on the conveyor and if the speed is properly regulated, prevents the distortion of large ware and the setting 'up of temperature strains in `small ware. The speed control also permits the utilization of the initial heatior heat contained in the ware asit leaves the mold or forming machine, in the heating of the leer itself, and as a result, less fuel is required in heating the leer.

Y It is also apparent that'the ware leaving the forming machine is delivered to a stationary portion of my conveyor, therefore the danger of having the ware upset and break on the conveyor, as frequently happens where the ware is delivered to 'a moving conveyor, is reduced to a minimum, l
